The following table describes each parameter under the sub-menu. Settings in boldface are the default and suggested values.

Parameter

Description System Performance The DRAM timing is controlled by the DRAM Timing Registers. The timings programmed into this register are dependent on the system design. Slower rates may be required in certain system designs to support loose layouts or slower memory. CAS Latency Setting When synchronous DRAM is installed, the number of clock cycles of CAS latency depends on the DRAM timing. Options Normal Mode Safe Mode Fast mode Turbo Mode Ultra Mode

2T, 2.5T, 3T

The other two parameters under the Advanced Chipset Features are presented below. Settings in boldface are the deafult and suggested values.

Parameter

Description Memory Hole at 15M-16M You can reserve this area of system memory for ISA adapter ROM. When this area is reserved, it cannot be cached. The user information of peripherals that need to use this area of system memory usually discuss their memory requirements.
